Abstract (en)

The present disclosure discloses a method and apparatus for data auditing. For each computing node, when performing a secure multi-party computation based on a search request, encrypted data sent by other computing nodes and / or encrypted data generated by the computing node itself as to-be-audited data can be stored in a trusted storage space, wherein when receiving subsequently an auditing request with respect to the search result corresponding to the search request, the agent can, based on the keys obtained from the respective computing nodes, decrypt the encrypted data included in the to-be-audited data obtained from the trusted storage space to obtain original data of the respective computing nodes, and audit the respective computing nodes based on the original data.
